The main terms of a contract are usually determined by both parties through consultation. The parties can determine the terms of the contract based on the type and nature of the contract. Sometimes the main terms of a contract are directly stipulated by law. When the law directly stipulates that a certain contract should have certain terms, these terms are the main terms.
